Image output
Raster image format
A pixel-based file format such as PNG, JPEG, or WebP, each with different compression, transparency, and compatibility characteristics.
Choose it according to transparency, file size, editing, print, and browser delivery requirements.
export a 3000 px wide PNG master and a quality-85 WebP delivery copyImage output
Lossless compression
Reduces file size while allowing the original encoded data to be reconstructed exactly.
Use it for masters, graphics, text, masks, repeated editing, and assets where compression artifacts are unacceptable.
use lossless compression, preserve sharp text edges and flat color areasImage output
Alpha channel
An additional channel that stores per-pixel transparency separately from color.
Use it for cutouts, overlays, compositing, motion graphics, and transparent backgrounds.
export with a clean straight alpha channel and fully transparent backgroundImage output
Color profile
Metadata that describes how numerical color values should be interpreted by displays, browsers, printers, and editing tools.
Embed a known profile to reduce unexpected color shifts between applications and devices.
embed the sRGB color profile for consistent web deliveryVideo output
Video container
A file wrapper such as MP4, MOV, or WebM that can hold encoded video, audio, subtitles, and metadata.
Choose it for playback compatibility, editing workflow, streaming, and required tracks.
deliver as an MP4 container with one video track, stereo audio, and embedded metadataVideo output
Video codec
A method for encoding and decoding video frames, affecting quality, file size, performance, and compatibility.
Select a codec that the target editor, device, browser, or platform can decode reliably.
encode the review copy with H.264 using a broadly compatible profileVideo output
Bitrate
The amount of encoded data used per second of audio or video, commonly measured in kbps or Mbps.
Balance bitrate against detail, motion complexity, upload limits, bandwidth, and storage.
target 12 Mbps video bitrate, preserve fine texture during fast motionVideo output
Delivery frame rate
The number of frames stored or presented each second in the delivered video.
Keep it consistent with source motion and platform requirements to avoid judder, duplicates, or unintended interpolation.
export at the source frame rate of 24 fps with constant frame rate timingVideo output
HDR
High Dynamic Range output stores a wider brightness and color range than standard dynamic range delivery.
Use it only when the full creation, grading, metadata, display, and distribution chain supports the chosen HDR format.
Incorrect HDR metadata or conversion can make output appear washed out, clipped, or too dark.
export an HDR master with the approved color space, transfer function, and mastering metadataAudio output
Sample rate
The number of audio samples stored per second, expressed in hertz or kilohertz.
Match the production and delivery workflow to avoid unnecessary resampling and timing problems.
export the video mix at 48 kHz sample rateAudio output
Audio bit depth
The number of bits used for each audio sample, influencing available dynamic range and processing headroom.
Use higher bit depth for production masters and an appropriate delivery setting for the destination.
export a 24-bit WAV master with no clippingAudio output
Integrated loudness
A measurement of perceived average loudness across an entire program, commonly expressed in LUFS.
Use it to meet platform, broadcast, podcast, or delivery loudness targets without relying only on peak level.
normalize the final mix to the delivery target in LUFS, preserve natural dynamicsAudio output
Audio stems
Separate grouped audio files such as dialogue, music, ambience, and sound effects that can be mixed independently.
Deliver them when localization, alternate mixes, mastering, or later editorial changes are expected.
export synchronized dialogue, music, ambience, and effects stems with identical start time3D output
3D interchange format
A format such as glTF, GLB, FBX, USD, or USDZ used to move geometry, materials, animation, and scene data between tools.
Choose it according to the destination engine, editor, web viewer, animation, and material support.
export as GLB with embedded materials and textures for web preview3D output
Texture packaging
The method used to embed, reference, name, and organize texture maps alongside a 3D asset.
Use it to prevent missing materials and broken paths when the asset moves between systems.
package all PBR texture maps with relative paths and consistent material namesMaster delivery
Master file
A highest-quality approved source used to create platform-specific, compressed, resized, or localized derivatives.
Preserve it with version, color, audio, rights, and provenance information before creating delivery copies.
archive the approved lossless master with version number, checksum, color profile, and metadata
